Even buying used? My A5 needed an overhaul because of neglect, and I see my M98 needing a new rear hammer ring, its pretty chewed up. My Sonix striker needed an O-ring but I just used a tank ring, which worked.

I got my A-5 BNIB back in '06. I upgraded to the nice o-rings years ago and have never had to replace one, not even the rear hammer.

This might be due to the fact that I completely strip, clean, and re-lube/oil my A-5 if I ever get shot in the marker. I hate paint residue with a passion. I've seen what happens to the black paint when paint gets left on for years without ever being cleaned off.

Also, I always add a drop or two of oil in the ASA before everyday of play, regardless of whether it needs it or not.

I haven't really bothered with my M98 because I don't want to play with it. I just want to paint it, get it back in pretty good condition (already polished the internals) and sell it.
